I've just installed Ubuntu om my desktop computer. I also installed BOINC and attached it to the bam account manager. Boinc didn't get any work from WCG and I remembered that WCG doesn't support account managers fully so I attached to WCG manually from the BOINC manager as well. Still no luck though. See the WCG related messages below.
Can anyone help?
